Organic farming
beats genetic engineering as response to global warming
The article
below argues that organic agriculture has the potential to reduce, mitigate,
and adapt to climate change impacts while remaining accessible to the
billions of subsistence farmers around the world. Research demonstrates
the ability of organic agriculture to both reduce greenhouse gas emissions
with fewer energy inputs and withstand climate change impacts like drought
with greater efficacy.
This
is in stark contrast to genetically engineered crops, such as Monsanto’s
drought-tolerant corn, which has yet to overcome technical and social
hurdles. While there may be yield increases during droughts, the crops
suffer yield losses when conditions are favourable. Given that increased
erratic weather patterns are a symptom of climate change, the author
points out that this is “clearly disastrous”.

Food security and
global warming: Monsanto versus organic

*Organic
farming beats genetically engineered corn as response to rising global
temperatures
This
week Science published research detailing the vast, global food-security
implications of warming temperatures. The colored graphics are nothing
short of terrifying when you realize the blotches of red and orange
covering the better part of the globe indicate significantly warmer
summers in coming decades.
The implications
of the article are clear -- we need to be utilizing agricultural methods
and crops that can withstand the potential myriad impacts of global
climate change, especially warmer temperatures. The article significantly
notes, "The probability exceeds 90 percent that by the end of the
century, the summer average temperature will exceed the hottest summer
on record throughout the tropics and subtropics. Because these regions
are home to about half of the world's population, the human consequences
of global climate change could be enormous."
Whether
you believe global warming is part of a "natural cycle" or
a man-made phenomenon is irrelevant. The bottom line is that our earth
is rapidly warming, and this is going to drastically affect our food
supply. We must undertake both the enormous task of reducing our carbon
emissions now to avert the worst, while at the same time adapting our
society to the vast and multitudinous effects of unavoidable global
climate change. Failing to do either will, as the Science article indicates,
have dire effects on a large portion of our world's population.
Determining
the best course of action for ensuring food security in the face of
global climate change remains a challenging task. Recognizing that climate
change is slated to affect developing countries and small-scale farmers
the most is a crucial point. Such understanding enables people to realize
that viable solutions must be accessible, affordable, and relevant to
the billions of small-scale farmers in the developing world. Unfortunately,
it appears that some of the solutions on the table fail to meet these
criteria.
Last
week, Monsanto made a big public relations splash by filing documents
with the FDA regarding a drought-tolerant GM corn variety it is developing
with a German company, BASF. Monsanto claims that in field trials, the
corn got 6-10 percent higher yields in drought-prone areas last year,
but the release is extremely short on details. Regardless of the reality,
Monsanto is presenting the corn as a way to help improve on-farm productivity
in other parts of the world, notably Africa.
Yet,
absent from the media hype were the many technical and social problems
with Monsanto's corn.
A little
over a year ago, the Australian Centre for Plant Functional Genomics
held a conference specific to drought and drought-tolerant crops. As
a follow up, the Australian government's Grains Research and Development
Corporation published a piece detailing the research shared and lessons
learned from the conference. One topic addressed was the potential of
GM drought-tolerant varieties. In the analysis stated, "The most
notable and problematic (effect) is the tendency of drought-tolerant
GM lines to not perform as well under favourable conditions. This appears
to be the case for CIMMYT's GM wheat and Monsanto's GM corn. The flaw
is a profound one. It amounts to shifting the yield losses experienced
in dry seasons onto the good years." In essence, farmers might
get a small bump in yield during droughts, but will suffer yield losses
when conditions are favorable. Considering that climate scientists continually
point to increased erratic weather patterns as a symptom of global
warming, this reality is clearly disastrous. Surely there must be better
solutions that increase production under all weather conditions.
One promising
solution appeared in an article published in BioScience in 2005. The
authors outlined the Rodale Institute's Farming Systems Trial, a long-term
comparison of organic and conventional farming systems conducted between
1981 and 2002. Significantly, the trials found that organic production
yielded equivalently to conventional systems after a transition period.
Yet even more importantly, Rodale found that in drought conditions in
which rainfall was 30 percent less than normal, organic systems yielded
28 to 34 percent higher than conventional systems. Rodale equates the
yield gain to increased water retention as a result of higher soil organic
carbon. Water volumes percolating through the various systems were 15-20
percent higher in the organic systems as compared with the conventional
systems over the 12 year period.
The BioScience
article additionally noted that the organic systems used 28 to 32 percent
fewer energy inputs, retained soil carbon and soil nitrogen better,
and offered a higher profitability over conventional systems. What is
so significant about this research is that it demonstrates the ability
of organic agriculture to both reduce greenhouse gas emissions with
fewer energy inputs and withstand climate change impacts like drought
with greater efficacy.
Most
importantly, it offers an economical and accessible form of agriculture
for billions of small-scale farmers. Scaling up agricultural development
in rural areas like Africa can be accomplished with organic methods like manure,
compost, and cover crops. Even the United Nations recognized the opportunity
presented by organic production in a report late last year. Conventional
breeding and improved seeds are also part of the solution. Between 1939
and 2005, conventional breeding contributed significantly to an almost
six-fold yield-gain in corn in the U.S.
This
point is crucial, since the seeds Monsanto is planning to release will
be owned by the company and sold at exorbitant prices. GMO seeds cost
from two to over four times as much as conventional seed varieties,
and the disparity is increasing. How will small-scale farmers pay for
such seeds? How will they pay for the chemicals and synthetic fertilizers
necessary for such production? Shouldn't we be looking for solutions
that are viable and realistic for those people who are most food insecure?
Monsanto does not have the answers here, but organic methods can and
should be a big part of the solution.
The future
of food security in the face of warming temperatures cannot be based
on a system of profits and research that fails to address the needs
of food-insecure farmers. We need real solutions that will enable farmers
to maintain and increase yields with those materials and techniques
already available to them with little extra cost: animal manure, increased
irrigation opportunities, cover crops, compost, and integrated pest-management
systems. Organic agriculture will reduce, mitigate, and adapt to climate
change impacts and still remain accessible and economic to the billions
of subsistence farmers around the world. If we really want to fight
the food crisis, let's start investing in and promoting organic production
today to ensure better climate adaptation in the future.
